MAY lighten up with being so head shy.Every BP is different, as is any creature. There are things some can tolerate more so then others. That's like someone trying to force feed Brussel Sprouts down my throat. Is that gonna make me like them, heck no. It's just gonna make me hate you for shoving Brussel Sprouts down my throat.
